Weeks-long disruptions to GPS signals in Israel’s airspace have ended, officials said on Friday, declining comment on an Army Radio report that Russian electronic warfare - possibly coming from Syria - was to blame.

The disruptions were noted in early June by civilian pilots and confirmed by the Israel Airports Authority (IAA), which said the matter was under investigation and that alternative navigation tools meant there was no safety risk.

An IAA spokesman said the problem had been resolved this week, but declined to elaborate on when or how.

Israeli Army Radio said Russian electronic warfare, possibly emanating from neighboring Syria where Moscow has been backing Damascus against rebel forces, was the cause. The Russian Embassy in Israel dismissed that report as “fake news”.

Zeev Elkin, an Israeli security cabinet minister who has taken part in diplomatic contacts with Russia, was asked whether the Army Radio report was true during an interview on Friday.

“I prefer not to answer that question,” he told Tel Aviv radio station 102 FM. “There were (GPS) disruptions. They vanished. That’s what’s important.”

Israel treads carefully in its relations with Russia, which has mostly turned a blind eye to Israeli air strikes against Iranian-linked targets in Syria.
